L- Designated letter for "Moderate Drizle"
Lake Breeze: Wind which forms over a lake and moves towards the land which developes during the day.
La-Niña:The opposite of El-NIÑO: A period of unusually low surface water temperatures in the Eastern & Central Tropical Pacific.
Latent: Means "Hidden": Hidden Heat..
Latent Heat: Heat which is absorbed or released by a substance during condensation, evaporation or sublimation.
Latent Heating: In the atmostpere, heat which is moved from one place to another due to the changes of phases of water.
1. Latent Heat Of Condensation
2. Latent Heat Of Deposition: Heat released to the atmosphere 680 calories.
3. Latent Heat Of Evaporation: Atmosphere absorbes 600 calories.
4. Latent Heat Of Fusion: Heat released to the atmosphere 80 calories.
5. Latent Of Melting: Atmosphere absorbes 80 calories
6. Latent Of Sublimation: Atmosphere absorbes 680 calories.
LCL: Lifting condensation Level: The level at which condensation forms. (Clouds)
Lee Wave Clouds: Clouds which form donwind at the creats of a mountain wave.
Lenticular Cloud: Clouds that are extremely high and are stationary that form by air flowing over mountains.
Lenticlar cloud over our house.
Lightning:
Lightning: Dart Leader: An electrical charged ionized channel which dart from the thunderstorm cloud to the
ground after the Stepped Leader has estabilished contact with the ground.
Lightning: Stepped Leaders: Streams of electrons which move from a thunderstorm cloud towards the ground in steps of about
300 feet and produce an ionized path.
When the Stepped Leader comes within about 300 feet of the ground it is
met by a charge from the ground to complete the path.
- 
6 feet above the ground reducing visibility below 7 miles.
Low Pressure: In low pressure the winds are "Counter-Clock-Wise" (CCW) in the Northern Hemisphere. Move inwards center seeking. "Centripetal Force".
LST: Local Standard Time.
